Abstract: Disclosed are a DNA oxidative damage repairing device and an application method thereof. The device is composed of an electrons emitting assembly, an electrons emitting electrode, a control system, a power source, a support and the like. The device emits electrons to a space in a certain range, negatively charged nano particles with certain density are formed in the space, the space is sterilized, and various hazardous substances in suspension space are eliminated. The negatively charged nano particles entering a body through a respiratory system release electrons carried by the particles, electrons lost due to oxidative damage are replenished to all parts of the body, and dormant state genes can also be repaired and activated. The two-way regulations function can play a role in broad spectrum medical treatment, so that diseases that cannot be cured through drugs easily are present are cured.

Abstract: A low-temperature preservation device with disinfection and fresh-keeping functions comprises low-temperature preservation spaces (11, 12, 13), an electron emission assembly (2), a refrigeration system, an electric system and a housing. The electron emission assembly (2) emits electrons to form negative electric nano particles with a certain density, thereby enabling the preservation spaces into a disinfection state. The negative electric nano particles attached to the surfaces of preserved articles, with water molecules, form hydration films on the preserved articles, so that water of the preserved articles is kept, bacteria and viruses on the surfaces of the preserved articles are killed, freshness of the preserved articles is kept, and the preservation time is prolonged.

Abstract: A device and method are provided for producing negatively charged nanoparticles. The device comprises a power supply, an electron supermicroemitter and a controller, the power supply connects with the electron supermicroemitter and the controller respectively. The potential of the electron supermicroemitter to the ground is controlled in the range of ?2 kV to ?29 kV by the power supply and the controller in accordance with the shape, size and different application of the materials of the emitter, so as to form field electron emitting of tunneling effect. The energy of electrons with high current density produced by the emitter can be adjusted during the electrons' colliding with particles in aerosol such that the electrons are attached to the nanoparticles of different size with wider energy band to form negatively charged nanoparticles.
